That aquatec gloss is pants, I've also told customers that I won't use it although on some of the bigger contract specify and supply it so I just do what they ask.
Tickle over between coats and use oil based paints for all woodwork, don't thin it with turps or white spirit either as it makes the gloss discolour faster. If you need it to flow a bit better add a product called "owatrol", it improves body and let's the gloss flow alot better reducing brush marks aswell.
Or....... Just pay me to do it. Lol
